SSL Certificate Forgery via MD5 Collision Attacks

Public key infrastructure PKI is a mechanism used for issuing digital certificates for secure websites. A critical vulnerability was detected in PKI that enables attackers to create a forged digital certificate that will be trusted by all common web browsers. The vulnerability is due to a weaknes...

MD5 vulnerable to collision attacks

Overview Weaknesses in the MD5 algorithm allow for collisions in output. As a result, attackers can generate cryptographic tokens or other data that illegitimately appear to be authentic. Description A secure cryptographic hash algorithm is one that generates a unique identifier of a fixed size...

Fake valid SSL certificate creation attack was successfully demonstrated

Valid fake SSL certificate creation attack was demonstratedby exploiting MD5 collisions and RapidSSL certificate generation procedures. The cost of attack is appoximately $2000...

fetchmail/mutt/evolution/...: APOP password disclosure vulnerability

The APOP protocol allows remote attackers to guess the first 3 characters of a password via man-in-the-middle MITM attacks that use crafted message IDs and MD5 collisions. NOTE: this design-level issue potentially affects all products that use APOP, including 1 Thunderbird 1.x before 1.5.0.12 and...

security flaw

The key serial number collision avoidance code in the keyallocserial function in Linux kernel 2.6.9 up to 2.6.20 allows local users to cause a denial of service crash via vectors that trigger a null dereference, as originally reported as "spinlock CPU recursion."...

security flaw

The page cache feature in Mozilla Firefox before 1.5.0.10 and 2.x before 2.0.0.2, and SeaMonkey before 1.0.8 can generate hash collisions that cause page data to be appended to the wrong page cache, which allows remote attackers to obtain sensitive information or enable further attack vectors whe...

CVE-2007-0006

The key serial number collision avoidance code in the keyallocserial function in Linux kernel 2.6.9 up to 2.6.20 allows local users to cause a denial of service crash via vectors that trigger a null dereference, as originally reported as "spinlock CPU recursion."...

Digipass Go3 Token Dumper (at least for 2006)

The initial reverse engineering of Vasco’s Digipass Go3 algorithm follows in C++. I think this implementation is a "rough" approximation, if we take some limitations about 2006 and the calculations made into account. Or I'm just joking… : This generator was able to predict an "otp" collision,...

OpenSSL Version Rollback and Weak Cryptographic Algorithm Vulnerabilities

OpenSSL contains vulnerabilities that could allow an unauthenticated, remote attacker to bypass security restrictions. The first vulnerability CVE-2005-2969 affects any application using a SL/TLS server implementation provided by OpenSSL versions 0.9.7g and prior. If these implementations have...

SHA family hash functions cryptographic weakness

Cryptographic weakness found making real strength against coliisions: collisions in the the full SHA-1 in 269 hash operations, much less than the brute-force attack of 280 operations based on the hash length. Collisions in SHA-0 in 239 operations. Collisions in 58-round SHA-1 in 233 operations...

SHA-1 Broken

HA-1 Broken SHA-1 has been broken. Not a reduced-round version. Not a simplified version. The real thing.
